Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 As shown, the present invention includes a heat exchanger shell 1, and the inside of the heat exchanger shell 1 is sequentially arranged as a gas phase flow guide area 2, a distribution area 3, a fin area 4 and a gas-liquid mixing flow guide area 5.

[0014] Such as figure 1 As shown, a wave-shaped gas-phase medium deflector 21 is arranged in the gas-phase diversion area 2, and a gas-phase inlet is arranged at the middle of the bottom of the heat exchanger shell 1 where the gas-phase diversion area 2 is located, and a gas-phase inlet is arranged outside the gas-phase inlet. The inlet head 22 is opened, the gas phase inlet head 22 is opened, the gas phase medium enters the gas phase guide area 2 through the gas phase inlet, and the gas phase medium enters the distribution area 3 through the action of the gas phase medium guide ...

Abstract

The invention relates to a distributor and a plate-fin heat exchanger with the same. The distributor comprises a distributor shell with an upper opening and a lower opening; a rectangular framework is arranged at the bottom of the distributor shell; a plurality of partition boards are vertically inserted into the distributor shell at intervals; the rectangular framework is divided into a plurality of air-phase channels through the partition boards; the distributor further comprises a liquid-phase channel; the liquid-phase channel is a rectangular pipe, is transversely arranged, and passes through the partition boards; liquid-phase inlets are formed in the distributor shell corresponding to the both ends of the liquid-phase channel; a liquid-phase inlet sealing head is arranged at the outer side of each liquid-phase inlet; a baffle partition part is arranged at the middle part inside the liquid-phase channel; a liquid outlet is formed at the top of the liquid channel between two adjacent partition boards; and a gas-liquid mixing channel is formed between the two partition boards above each liquid outlet. With the adoption of the distributor provided by the invention, the requirements of gas-liquid distribution and normal working in an offshore shaking condition can be met. The distributor can be widely applied to liquefied natural gas FPSO (Floating Production Storage and Offloading) in the offshore shaking condition.

Description

technical field [0001] The invention relates to a distributor and a heat exchanger with the distributor, in particular to a distributor suitable for offshore floating environments and a plate-fin heat exchanger with the distributor. Background technique [0002] As we all know, as an independent liquefied natural gas FPSO (Floating Production Storage and Offloading, floating oil storage and offloading device), all processes and equipment must have the basic characteristics of land in principle. Among them, the layout of the pretreatment unit and the liquefaction process unit is the most concentrated embodiment of the number of equipment and space requirements in the FPSO; at the same time, the normal operation and performance of key equipment are also affected to a certain extent in the offshore sloshing environment. In order to adapt the whole process system to the sea conditions, the study of the sea adaptability of the key equipment is also a matter of great concern. [...
